Member Function Documentation

◆ preDumpStats()

void BaseTags::BaseTagStats::preDumpStats ( )

overridevirtual

Callback before stats are dumped.

This can be overridden by objects that need to perform calculations in addition to the capabiltiies implemented in the stat framework.

Reimplemented from Stats::Group.

Definition at line 273 of file base.cc.

References BaseTags::computeStats(), Stats::Group::preDumpStats(), and tags.

◆ regStats()

void BaseTags::BaseTagStats::regStats ( )

overridevirtual

Callback to set stat parameters.

This callback is typically used for complex stats (e.g., distributions) that need parameters in addition to a name and a description. Stat names and descriptions should typically be set from the constructor usingo from the constructor using the ADD_STAT macro.

Reimplemented from Stats::Group.

Stats::Scalar BaseTags::BaseTagStats::dataAccesses

Number of data blocks consulted over all accesses.
